[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] like Figures 1 to 3 The yarn width detection device in dry fiber shown includes a bracket 1 and a box cover 2, and also includes: a wire passing tube 3, located in the middle of the bracket 1; a long light source 4, located in the middle of the wire passing tube 3; a camera, located on the inner side surfaces of the upper and lower sides of the bracket 1; wherein, a tube clamp 6 is provided at each end of the wire passing tube 3; a light source bracket 7 is provided at each end of the long light source 4; and a camera mounting plate 8 is provided on the side of the camera 5.

[0027] The implementation process of the utility model is that the yarn passes through the visual window on the box cover 2, passes through the wire tube 3, uses the long light source 4 as the background, and uses the cameras 5 on the upper and lower sides to shoot the passing, and uses the standard block to calculate the ratio of the actual size to the screen size, and then takes the smallest rectangle of the yarn, calculates the width of the rectangle, and thus calculates the width of the yarn. The utility model uses a strong light background to control the change of ambient light, prevents the yarn from reflecting light, and gray value changes and misreports of size, thereby recording the width of the carbon fiber yarn for statistical use, to check whether the material is qualified, and to prevent cracks in the preparation of dry fibers.

[0028] In the utility model, a visual window is provided in the middle of the box cover 2 to ensure that the yarn can pass through the entire device. The visual window allows the operator to directly observe the state of the yarn and perform inspection without opening the box cover, which greatly simplifies the operation process and improves work efficiency.

[0029] On the basis of the above, there are eight wire tubes 3 in total, two in one layer, and a total of four layers distributed in the middle of the bracket 1. This can maximize the guarantee that the yarns can avoid mutual interference during operation, thereby ensuring the number and efficiency of yarn passing.

[0030] In this solution, two long light sources 4 are respectively located under the first and third layers of the wire tubes 3. This layout allows the light to be more evenly irradiated onto the subject, avoiding the problem of heavy shadows or insufficient light caused by over-concentration or over-dispersion of the light source. The two long light sources 4 are arranged back to back, so that the cameras on the upper and lower sides can obtain sufficient strong light background, thereby improving the contrast and three-dimensional sense of the photo.

[0031] In the present invention, the strip light source 4 and the light source bracket 7 are connected by a threaded hole. The advantage of this connection method is that it can ensure the close fit between the strip light source and the light source bracket, avoiding the problem of weak background light due to looseness. At the same time, the design of the threaded hole also allows the light source to be fine-tuned according to actual needs, thereby improving the flexibility of the lighting system.

[0032] In the preferred embodiment of the utility model, the pipe clamp plate 6 and the light source bracket 7 are fixedly connected to the bracket 1 through the square tube column 9. This connection method has strong stability, strong load-bearing capacity, easy installation, and strong adaptability. The length and quantity can be adjusted according to actual needs to adapt to wire pipes of different sizes and shapes, and maintenance is also relatively convenient.

[0033] In this solution, the camera 5 and the camera mounting plate 8 are connected through threaded holes, so that the height and angle of the camera can be adjusted as needed. The camera mounting plate 8 is fixedly connected to the bracket 1 through the camera adjustment plate 1 to ensure the fixation of the camera 8, thereby ensuring the clarity of the captured image and avoiding the problem of unclear captured images due to camera shaking.

[0034] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
